Everything worked out! Thank you. I immediately deleted the extra content. But I don’t know how to make such a page for myself now? I need to create a new page, select a parent template... I choose home > edit it in elementor > and see a blank page. Hm ~

In this case, I believe you already have a page named Home, that has slug "home". Try to find it and either delete it(also from trash) or just rename its slug to something else. Then"home" from Lagoon should import.

Let me explain how to solve it in the future:1) Go to a page details of a selected page and change these settings: http://nimb.ws/3n01zk2) Open the elementor. Every section on this page must have the "Stretch section" set to "No" ( http://nimb.ws/4urxXW )
